Time for education.
I decided I needed an extra bit of light for those long desolate highways when you're the only one on the road, and deer seem to love hiding in the ditches.
So I decided on the windshield mount location, and I wanted a clean install so factory fog light switch it is.
Factory Fog Light Switch: I added on some extra wire, in the factory colors.
Then i pulled the dash apart and took the switch mounting plate off to get me here:
Now I decided to pop out the plug for the auto transmission, its of no use to me with my 5 speed.
To get these out you pry at the top and bottom.
I did some testing on these wires to find the the wires at the far ends are for the dash illumination.
I stripped some of the insulation away to attach the switch illumination here.
So far so good
Now that the switch lit up when I turned the lights on, I needed to make it functional.
I needed a switched 12v source, I found one, well a lot of them actually. I decided to carefully remove one of these power strips from the back of my fuse box to get some switched 12v sources.
Taking this thing out is a total PITA, so make it worth your while.
Bare in mind, those 12v Switched sources are NOT fused, so be sure to add a fuse, (In the picture it's a 15, Way over kill, I'm running a 3 in there now)
Now that purple wire goes from a switched 12v source to the purple wire on the switch, this is our 12v "In".
Now that we have an "In" we need an "Out".
I had to find a good way to get a wire through the firewall. I did so by poking a small hole in this rubber grommet.
The backside of the same grommet, (Driver side top left corner, where the windshield wiper wiring goes through the firewall.)
The wire that came through the grommet our "Out" wire connects to the LT BLUE wire on the switch. After I did that I bundled up the OD cut off plug and the fog light switch wires and taped them up.
Now the method to the madness.
The purple wire carries the electricity into the switch. When the switch is in the off position, electricity can't get past the switch itself. When you put the switch into the on position, electricity can come "In" and go "Out". So the electricity goes out on the Light Blue wire and up to the relay I added.
I picked this spot because it's easy to get to, and it's centrally located between the two lights. Not to mention this was an easy spot to drill a hole in, and know you're not going to have water leak in, or puncture something.
That is a 30 Amp Relay, I made a little rubber washer to go between the back of the relay and the metal, then screwed it down.
Now to get the "Feed" to the relay, I just went here. Easy to get to, and not attached to the battery.
I drilled a small hole in the fire wall pretty close to where the relay is. This gets a small rubber grommet of its own.
There you can see the hole, it's the one on the right side of the picture. You can also see I put a fuse for the relay in here, the goal here is to hide the wiring as best I can to give it a factory appearance.
